Step-by-step explanation:

The Volume is given by the following equation: V= Base x Height

Therefore,  [tex]V = 16\frac{1}{4} * \frac{1}{2} = \frac{65}{4} * \frac{1}{2} = \frac{65}{8} = 8\frac{1}{8}[/tex] units

Answer:

[tex]\boxed{(-1,4)}[/tex]

Step-by-step explanation:

The point is located in Quadrant II of the graph, where x-values are negative and y-values are positive.

Each marking on the graph represents one unit of distance. The two axes meet at the origin, where the coordinate point is equal to [tex](0,0)[/tex].

So, you can count backwards once from the origin to get your x-value ⇒ [tex]-1[/tex] and count up upwards four times from [tex]x=-1[/tex] to get your y-value ⇒ [tex]4[/tex].

Finally, place these in a coordinate point [tex](x,y)[/tex] ⇒ [tex]\boxed{(-1,4)}[/tex].

Answer:

(-1, 4)

Step-by-step explanation:

The point lies on the line x = -1.

The point lies on the line y = 4.

Where both lines intersect, that is the coordinate.

Answer:

the third one

Step-by-step explanation:

try to factor them and if it cannot be factored then it is prime

the only one that cannot be factered is the one you have highlighted so that is correct.

Answer:

The first one isn't the second one is.

Step-by-step explanation:

In the first one, they have to be equal because they're corresponding angles so m and n are parallel.

In the second one, m<2 and m<3 would be supplementary and add up to 180 degrees if the lines were parallel and since they don't add up to 180, the lines are not parallel.

Answer:

  y = 4

Step-by-step explanation:

The line x=8 is a vertical line. The perpendicular line will be horizontal, with a slope of 0. In order for it to go through the given point, the y-intercept must match the y-value of the point. The equation is ...

  y = 0x +4 . . . . . slope-intercept form with slope explicitly shown as 0

This simplifies to ...

  y = 4

600 blocks

Step-by-step explanation:

Well this question is asking us to find the volume of the rectangular prism.

Dimensions)

L: 12

W: 10

H:5

The formula for the volume of a rectangular prism is l*w*h or B*h.

So 12*10 = 120

120 * 5 = 600 blocks

Thus,

the fort contains 600 blocks.

Hope this helps :)

Answer:

[tex]\boxed{280\ blocks}[/tex]

Step-by-step explanation:

The blocks at the base are:

Length * Width = 10 * 12 = 120 blocks

On the 2nd Layer:

=> 9+11+9+11 = 40 blocks

There are 3 more layers as the 2nd layer:

So, the blocks of these 4 layers are => 4 * 40 = 160 blocks

Total Blocks = Base Blocks + Layer Blocks

=> 120 + 160

=> 280 blocks

A parallelogram is a quadrilateral with two pairs of parallel sides.

Option A is the correct answer.

Parallelogram is a quadrilateral that has two pairs of parallel sides.

In a parallelogram, opposite sides and angles are equal.

The adjacent angles add up to 180 degrees.

We have,

A parallelogram is a quadrilateral with two pairs of parallel sides.

So, option A is a valid reason for the given quadrilateral to be a parallelogram.

The other options do not necessarily hold true for all parallelograms. For example, the diagonals of a parallelogram bisect each other and are congruent, but not all quadrilaterals with bisecting diagonals are parallelograms.

Similarly, not all parallelograms have congruent diagonals or congruent opposite sides.

Thus,

A parallelogram is a quadrilateral with two pairs of parallel sides.

I'm pretty sure it's the last one that is incorrect

Step-by-step explanation:

Answer:

The first one - “line segment TA is congruent to line segment DO” is incorrect

Step-by-step explanation:

Since the triangles are similar, the angle measurements would be the same (congruent), but the line segments are are only similar, not congruent, as they have different lengths. So the first statement is incorrect.  

Answer:

The answer is 39.

Step-by-step explanation:

You have to substitute the value of x into the expression :

[tex]3x + 12[/tex]

[tex]let \: x = 9[/tex]

[tex]3(9) + 12 = 27 + 12 = 39[/tex]

Answer:

39

Step-by-step explanation:

To solve your question we must replace x with the given number which is 9 so,

3 (9) +12 =

We can now solve it by multiplying 3 * 9 which will give us 27. Then we can add 27 to 12.

Step-by-step explanation:

  Pabp = AB +BP +AP

  Papc = AP +PC +CA

So the sum of perimeters of the two smaller triangles is ...

  Pabp +Papc = AB +BP +AP + AP +PC +CA

  = (AB +BP +PC +CA) +2AP

  = Pabc +2AP

Filling in numbers, we have ...

  30 +35 = 45 +2AP

  20 = 2AP . . . . subtract 45

  10 = AP . . . . . . divide by 2

The length of AP is 10 units.

Answer:

$980

Nvm you have to multiply 98 by 10 since there are 10 participants. :)

Step-by-step explanation:

Well, first we wanted to find how much the morning classes cost together. You have to $28 multiplied with 75/100. I am multiplying it with 75/100 instead of 25/100 because the discount cuts off the 25% and the 75% is what you still have to pay. This will give you 2100/100 which is $21. Now you have to multiply $21 with 2 since there are two morning classes. $21 x 2 equals $42. Total for Morning Classes is $42.

Now the other two classes don't have a discount. So all you have to do is $28 x 2 or $28 + $28. This gives you $56. Total for The Other Classes is $56.

Last Step:

Total for Morning Classes + Total for the Other Classes = $56 + $42

                                                                                             = $98

Hope that helped! :)

Answer:

$ 980

Step-by-step explanation:

Discount for morning session = 25 % of 28 = 0.25 * 28 = $ 7

Fees for morning class = 28 - 7 = $ 21

Maximum people in one session = 10

Money earned in the morning sessions = 2 * 21 * 10 = $ 420

Money earned in the evening sessions = 2 * 28 * 10 = $ 560

Total money earned that day = 420 + 560 = $ 980

Answer: -third

Step-by-step explanation:

Answer:

x | 0 | 1 | 2 | 3

f(x) | - 7 | 0 | 5 | 8

Step-by-step explanation:

When you reflect a point say across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). Therefore if the function f( x ) is reflected across the x - axis, it's new function would be y = - f( x ). This new function is function g, so you can also say y = - g( x ).

Given the following table ...

x | 0 | 1 | 2 | 3

f(x) | 7 | 0 | - 5 | - 8 ... we can keep the x - values constant, but take the opposite of each y - value, or " f( x ). " Doing so the new table should be the following -

x | 0 | 1 | 2 | 3

f(x) | - 7 | 0 | 5 | 8 ... note that 0 remains constant as you can't take it's opposite, it remains zero. Therefore, the function g is represented by the above table.

The values of g(x) are as follows:

x    | 0 | 1 | 2 | 3

g(x) | -7 | 0 | 5 |  8

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).

As per the given data:

We are given a function f(x) and a table where the values of f(x) at different values of x is given.

The table for the values is as follows:

x    | 0 | 1 | 2 | 3

f(x) | 7 | 0 |-5 | -8

We have to find the values for the function g(x) which is obtained when f(x) is reflected about the x-axis.

When any function is reflected about the x-axis, the values of the y-axis will have their signs changed, i.e. the y-axis values will become -ve if they are positive and +ve if they are -ve.

For g(x):

x    | 0 | 1 | 2 | 3

g(x) | -7 | 0 | 5 |  8

Hence, the values of g(x) are as follows:

x    | 0 | 1 | 2 | 3

g(x) | -7 | 0 | 5 |  8
